The survey examined 235 organizations in 19 industries, ranging from fast-food companies to credit unions and cable service providers.

The 10,000 U.S. consumers who participated were asked to rate their recent customer service experience on a scale from one (very dissatisfied) to seven (very satisfied). Temkin then calculated the score for each organization by subtracting the percentage of consumers who gave marks of one, two or three from the percentage who gave a six or seven.

Ranking higher than the supermarkets and specialty grocers was Dollar Tree, which recently raised the stakes on grocery competition by announcing plans to add refrigerated and frozen food to 550 of its stores this year.
